To evaluate the efficacy of corneal stromal lens implantation in correcting hyperopia.

This was a retrospective case series study.A total of 16 eyes of 14 cases of hyperopia in the 989 Hospital of Chinese People’s Liberation Army received corneal stromal lens implantation from Jun. 2018 to Jun. 2021 were included.The range of preoperative spherical equivalent was 1.50 D-5.0 D, with an average of (3.61±1.08)D. All cases were followed up for 6 months.Uncorrected visual acuity, refraction and corneal endothelial cells density were compared before and after operation.

No intraoperative or postoperative complication was found. At 6 months after surgery, uncorrected distance visual acuity (UCDVA) improved from 0.61±0.30 to 0.47±0.19 (t=3.64, P=0.003), and uncorrected near visual acuity (UCNVA) improved from 0.66±0.30 to 0.26±0.11 (t=5.83, P<0.001). The UCNVA improved by more than two lines in 14 eyes (87.5%) at 6 months after surgery. Mild overcorrection was observed at 1 month after operation, and refractive power was stable at 3 months later. The average residual spherical equivalent was (0.74±0.29)D, which decreased significantly from (3.61±1.08)D before surgery (t=9.45, P<0.001). There was no obvious hyperopic regression at 3 and 6 months after surgery. There was no significant decrease in corneal endothelial cells density at 1 week, 1 month, 3 months and 6 months after operation (F=1.76, P=0.128).

Corneal stromal lens implantation can be used to correct hyperopic eyes with good safety, effectiveness and predictability, providing a new choice for hyperopic patients.
